Sarah Thompson is the Pink Ninja Steel Ranger from Power Rangers Ninja Steel. She is also Brody Romero's love interest.
As a new student at Summer Cove High, arriving on her handmade hoverboard, she runs into class nerd Monty and Victor, the class president and jock. After Victor tries to use her hoverboard and crashes into Preston's magic show she and Preston notice objects falling from the sky. She and Preston go to investigate and save Brody Romero, a young man who had just escaped from the evil Galvanax, from an alien called Korvaka. The three of them then pull out three of the Ninja Power Stars from the Ninja Nexus Prism and become Power Rangers, with Sarah becoming the pink ranger.
Sarah is the brains of the team and an adrenaline junkie. She intends to be a great engineer and is the person who designs gadgets whenever the Power Rangers need them!
She also is willing to take on as many extracurriculars so as to look good in a college application, as seen on Hack Attack when she joins the Track and Field Club, the Chess Club, the Camping Club and the Archery Club.
She can get carried away by these things and ultimately using them for good or bad pro. She can be unfocused but it is not her to blame, seeing as she applied for four things at once.
- Sarah is very similar to Riley Griffin and Noah Carver from the last two seasons in which they are smart and serious.
- Sarah is the first Ranger to have the same name of a Power Rangers actress, Sarah Thomson, who portrayed Fran in Power Rangers Jungle Fury, despite only one letter different with "Thompson" and "Thomson."
- Sarah is the only one of the team to have not used a Mega Morph Cycle as of Hack Attack.
- Sarah is described to by fans as one of the "realest rangers ever", due to the fact that she applied for four clubs to look good when applying to a college.
